Solution

The correct option is D Atherosclerosis
In atherosclerosis, the fat is deposited in the tunica media layer of the blood vessel. This leads to narrowing of the lumen of the blood vessel. Hence, the blood flow in atherosclerotic vessel is reduced. Overtime the fat deposits get hardened forming hard sclerotic plaques. The arterial walls become stiff loses the capacity to pump blood.
